Dell PowerStore Protecting Your Data

High availability is supported (but not guaranteed) for remote backup sessions and retrieve sessions but not for instant access sessions:

• When a node is down or a node reboots -
  • Backup and retrieve sessions failover to the peer node and continue on it.
  • Instant access sessions are node-specific. When the node on which the session is running is unreachable or down, the session moves to a failed state. Unmap the volume from the host and delete the session, and then create the session again.
• When an appliance powers off or reboots -
  • All backup and retrieve sessions resume when the appliance is up again.
  • Instant access sessions move to a failed state. Unmap the volume from the host and delete the session, and then create the session again.
